Tunnels are transport, right? :-)

The earliest RFC I was involved with, that made distinctions about what you
can get away with on the public internet versus in a managed network, was
https://tools.ietf.org/html/rfc7510#section-5. This was negotiated after a
fairly vigorous back-and-forth between transport people and non-transport
people during IETF Last Call.

We put together a design team with a few people to try to work through this
for the myriad other protocols that people wanted to tunnel over UDP, once
and for all.

https://tools.ietf.org/html/rfc8084 was published as a BCP.

I may be forgetting other stuff, of course.

Best,

Spencer
